Abstract: A cable joint for high voltage electric power cables (10, 20) and with an improved smooth screen connection is provided. This cable joint is formed by first applying a cold shrinkable insulating joint-body (5) over a semiconductive plate covering a junction connector and ends of the semi-conductive screens (13, 23) of the cable. A copper mesh (9) is then provided over this insulating joint-body. Ends of the wires of the wired-screens (12, 22) of the cables are bent back over the copper mesh and spread so as to cover the whole circumference thereof. A copper plate (30) is then rolled around the joint, covering the conductive wires of the wired-screens. Finally, a cold shrinkable insulating joint-cover (3) is applied over the joint, covering and exerting a permanent pressure onto the conductive plate (30) over the wires of the wired-screens (12, 22). Because the wire are equally distributed over the perimeter of the copper mesh, the joint has a smooth design with a constant diameter.

Abstract: A semi-conductive tubular assembly (30) or molded rubber cap is used in a cable joint for medium voltage electric power cables (10, 20). The conductors (13, 23) of the cables are connected together by a connector (40) constituted by a bolted contact assembly having a tubular shape and wherein the conductor ends are maintained by bolts. Two rubber caps (30a, 30b) preferably overlap each other in the middle of the connector. Each cap has an internal shape adapted to compensate for the gap resulting from the difference in diameter between the conductor insulation and the connector, as well as for the eccentric position of the latter with respect to the conductors. By mating the change of shape (31a, 31b) between the underlying connector (40) and the conductor insulation (12, 22), the caps provide a relatively cheap and efficient solution for an electrically reliable product, e.g. by reducing local electric stresses.

Abstract: A joint adapted to ensure the interconnection of two electrical cables, each cable including a central conductor, an insulation layer (1), a semi-conductive coating layer (2), a metallic cable screen (3) and an outer cable jacket (4). The joint includes mechanically shrink-fittable materials adapted to ensure, when shrunken, a dielectric continuation (5) of the insulation layer, a continuation of the cable screen by a metallic joint screen (6), and an outer protection (7). The invention more particularly concentrates on an improvement of the screen continuation of the cable. The joint includes therefore, a layer of conductive material (9) placed underneath the metallic cable screen (3) at the location where this cable screen is in contact with the joint screen (6). As a result, the joint shows a relatively low electrical resistance between the cable screen and the joint screen, is cost effective and is easy to install.

Abstract: Joint between two electrical cables and protection element therefore. A joint between two electrical cables (1) having stripped end portions. The joint comprises electrical and mechanical connection means (2) connecting both end portions of the cables, a first electrical insulating sleeve (3) mounted on the connection means and the stripped end portions, a second sealing sleeve (4) surrounding the first sleeve (3) and extending on both sides of the first sleeve (3) on said cables (1), and a supplemental and impact-resistant protection element (5) surrounding at least both end portions of the second sleeve (4). The supplemental, impact-resistant protection element (5) comprises at least two layers (11,12): a hard external layer (11) to avoid initial cutting of the object causing the impact, and another layer (12) that is shock-absorbing at the inner side of the first layer (11).

Abstract: A cable joint for inter-connecting two power cables (1, 2) in a junction body (3) which is made water impervious and is electrically shielded by a two part metallic member (14; 15, 16) that is connected to the lead sheaths or metallic screens (8, 9) of the power cables. The shielding is however interrupted by a shield break (17) located next to the junction body, and a grounding connection and/or cross-bonding cable is electrically connected to each part of the member, i.e. at both sides of the shield break. This cable may be of the 2-single-core or of the coaxial type and all the grounding earthing connections and/or cross-bonding are concentrated at one end of the cable joint. An insulated conductor (20) runs from one end to the other of the cable joint over the junction body (3) but inside the metallic member.

Abstract: A high-voltage cable joint for interconnecting terminus of conductors (4; 5) of a first (1) and a second (2) power cable, each cable having a metallic screen (10; 11) separated from the conductor by an insulation layer (6; 7) and a semi conductive layer (8/9). The cable joint includes a junction body (3) that is an insulated box wherein the conductors are interconnected. The metallic screen (10) of the first power cable (1) is electrically connected to one end of a first metallic tubular shielding member (19) of which the other end extends beyond the junction body. This member (19) is separated from the junction body by an insulation shield-break sleeve (22) and both have an end overhanging beyond the end of the junction body.
